I'd get new ones, nothing to modify.

I think the JBAs definitely help a little bit. From the stock 04 ECSB 5.3 dyno numbers I've seen, I've gained over 20 - 30 rwhp with I/H/E, and E-Fans, and I don't have the updated elbow from Volant. My last dyno was 270 rwhp 283 rwtq (with AC on incidentally). My underhood temps are definitely lower with the JBA's (ceramic/titanium coated) than with the stock cast iron's. Oh and I'm also on 20's with 275/55/20 tires.
